I tan in the beds too!  I'm fair skinned so I tan that way I don't burn in the sun.  Starting out I tan 6 days a week.  I work myself up to 20 mins.  Once I reach 20 mins, I then go to 2 to 3 days a week to maintain it.  I use Brown Envy (has a slight bronzer in it).  Then move on to Emerald Bay's Mojo with a tingle factor of 7.  
 
This year I stopped for a week and lost just about all of my tan so I'm having to restart again.  Now I am using Brown Envy Dark (it has more of a bronzer than the original).  Tanning is me time and I get to relax! 

  I might even get to squeeze in a nap at that time too!
